Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616908, here are decompositions:

5 + 31616903 = 31616908
17 + 31616891 = 31616908
179 + 31616729 = 31616908
347 + 31616561 = 31616908
569 + 31616339 = 31616908
647 + 31616261 = 31616908
677 + 31616231 = 31616908
839 + 31616069 = 31616908

Showing the first eight; more decompositions exist.
